The advantages of VGA transmission technology

Using differential technology itself is strong anti-jamming performance, plus some technical processing, interference is greatly improved. Even the harshest plant strong electric magnetic environments can use it to transmit VGA video over long distances. Immunity is an important indicator to ensure project quality, how to ensure the immunity of products on the show circuit design level of R & D personnel. Different products interference effect is not the same, conditional user in selecting the best time to do first products interfere with the test, there is no condition of user best spot in the field or worse than the case of a re-test stereotypes purchase. So as to ensure the quality of the project approved by Party to ensure a pleasant cooperation. Wire mesh lines drawn with cheap, crystal head production than VGA or RGB cable welding easy, soft wire, wiring is also convenient. VGA video extender and VGA long drive the price difference is not large, the greater the distance, the lower the cost wire, interference contrast better, more cost-effective. VGA Video Extender over long distances can be said to replace the HDMI Cable signal amplifier is a trend.
Technology is constantly progressive, twisted pair transmission technology is in progress! When VGA video transmission technology can be used to solve UTP transmission, the technical staff and thinking about whether you can use a twisted pair to transmit more signals: network cable there are only four pairs of twisted pair, VGA signal inside the RGB sub 3 twisted pair transmission, leaving a pair of transmission HV signal, when we also need a computer when other functions, this approach does not. Technical staff will be H / V signal re-encoding, which mixed RGB signals transmitted to the receiver side and then decoded. This only needs to be completed three pairs of VGA R / G / B / H / V five kinds of signal transmission. We saved a pair of lines can transmit audio or RS485 signals or mouse and keyboard signals, or even a USB signal. Of course, simultaneous transmission of three mouse and keyboard VGA signal, higher technical difficulty, the required stronger anti-interference.
